Bagua Zhang:

Bagua zhang (eight diagram palm) was developed by culmination and refinement of the most sophisticated principles geared from the previous millennia of martial arts evolution.

It was developed specifically for the Chinese police and body guards by Dong Hai Quan - a Daoist scholar in the early 19th century.

In Bagua Zhang, the feet walk and turn continuously like a swimming dragon, the postures move quickly, the strokes and gestures change swiftly. The result is a visually impressive martial art; light but not floating, deep, but not stagnant.
